Merge branch 'for-3.13-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata
Pull libata fixes from Tejun Heo:
"There's one interseting commit - "libata, freezer: avoid block device
removal while system is frozen". It's an ugly hack working around a
deadlock condition between driver core resume and block layer device
removal paths through freezer which was made more reproducible by
writeback being converted to workqueue some releases ago. The bug has
nothing to do with libata but it's just an workaround which is easy to
backport. After discussion, Rafael and I seem to agree that we don't
really need kernel freezables - both kthread and workqueue. There are
few specific workqueues which constitute PM operations and require
freezing, which will be converted to use workqueue_set_max_active()
instead. All other kernel freezer uses are planned to be removed,
followed by the removal of kthread and workqueue freezer support,
hopefully.
Others are device-specific fixes. The most notable is the addition of
NO_NCQ_TRIM which is used to disable queued TRIM commands to Micro
M500 SSDs which otherwise suffers data corruption"
